Remarks

• Systematics: This species is close to C. ficoides (Hamon & Kosztarab, 1979). Like C. deklei and C. russellae,C. kalmiae has its 8-shaped pores on the dorsum arranged in a lattice-like pattern, as also found in species of Cerochiton. However, the structure of the apices of the stigmatic pore bands is very different from that on Cerochiton species, and C. kalmiae has the broader tubular ducts on the dorsum restricted to just anterior to the anal plate and so has only one size of dorsal tubular ducts medially on the cephalothorax.
• Structure: Female test is convex, pyriform and reddish brown. Male test is elliptical, brownish yellow to red. Adult body is pear shaped (Lambdin & Kosztarab, 1977a). The adult female of C. kalmiae is characterised by the following combination of character-states: (i) 8-shaped pores on dorsum in a lattice-like pattern; (ii) 8-shaped pores on dorsum of two sizes, both quite small; (iii) larger pores restricted to near stigmatic pore bands and along margins; smaller 8-shaped pores frequent elsewhere on dorsum; (iv) cribriform plates present in a transverse band of 17–32 on abdominal segment IV; (v) tubular ducts of two sizes, broader ducts restricted to posterior abdominal segments; narrower ducts frequent elsewhere; (vi) multilocular disc-pores present in narrow bands one or two pores wide across abdominal segments II–VIII and metathorax; (vii) stigmatic pore bands bifurcated; (viii) stigmatic pore bands with few spiracular disc-pores, and (ix) leg stubs perhaps present (Lambdin & Kosztarab, 1977a) or absent (Hodgson & Williams, 2016).
• Biology: This species is often associated with Eriococcus azaleae. Tomlinson (1957) states that this is a single-brooded species that matures and lays eggs in fall, overwinters as eggs, and hatches in late May. Crawlers occur on leaves and mature by late summer.
• Economic Importance: Tomlinson (1957) provides chemical control methods that are safe to cranberries. This species is most likely to damage bogs that are never flooded.
• General Remarks: Detailed description and illustration by Lambdin & Kosztarab (1977a). Hamon & Kosztarab (1979) provide a detailed description and illustration of the first instar.
